Numerical and Experimental Study of the Airflow in a Square Section Bifurcation

Bifurcating geometries are ubiquitous in many natural and engineered systems, ranging from air conditioning units to biological respiratory pathways. The study of such geometries is of paramount importance to ensure the optimal performance and functionality of the system under investigation. This study centers on the medical aspect, specifically, the bifurcating geometry of the human trachea. A 3D-printed model of a bifurcation with comparable dimensions to the trachea was utilized to perform a range of measurements and visualizations. The paper is dedicated to the experimental studies and numerical simulations of the airflow in a 3D bifurcation with a square section.
